Senior Software Engineer - Applied AI & Cloud

I turn messy real-world data into production AI products.

Built on solid Python, FastAPI, and Java backends, with a track record of large-scale AWS migrations and cost-efficient systems.

Portrait of Nicolas Augis

Senior software engineer with 8 years of experience across France and Canada, now focused on Applied AI and Cloud. I build production-grade LLM pipelines and ship AI-powered products end to end.

My specialty: turning messy, unstructured real-world data into structured, actionable output that lives inside a real product. I have built this same pattern twice, for construction documents and for financial-market news, using multi-stage LLM pipelines, prompt engineering and structured JSON generation, on top of solid backend and cloud foundations.

Polisnap

polisnap.app

An iOS market-intelligence app I own end to end.

A SwiftUI/MVVM client backed by two Python/FastAPI services and Supabase/Postgres.

Its two-stage LLM pipeline uses a lightweight classifier to gate market-relevant content before a larger model generates structured impact reports, matched to each user's portfolio for personalized push alerts. The classifier gating keeps inference fast and cost-efficient.

Built with agentic development workflows, deployed on Fly.io with AWS on the roadmap.

Experience

Autodesk

Montreal, Canada

Large-scale data migration and cold-storage management on AWS.

Dec 2025 - Mar 2026

Software Engineer

  • Built a Python pipeline to migrate high-volume columns from DynamoDB to compressed Parquet files on S3, moving rarely-used data to lower-cost storage, relieving tables whose size and maintenance cost in DynamoDB had become unsustainable.
  • Designed an automatic TTL-based tiering mechanism: once a column goes untouched past a defined TTL window, its content is offloaded to Parquet and the original record in DynamoDB is replaced by a lightweight pointer to its new storage location.
  • Defined how the archived data is partitioned and addressed, and updated the data model so it can still be retrieved efficiently once moved out of DynamoDB.
  • Made the migration safe to resume after a partial failure through a checkpointing system, validated with unit and integration tests run against real production data extracts.
  • Reduced migration cost and improved throughput by benchmarking compression options (storage size vs. read speed) and comparing AWS API approaches to minimize read/write operations, with key trade-offs documented in RFCs alongside platform architects.

Storia Technologies

An LLM-powered document-processing and chatbot platform.

Jan 2025 - Sep 2025

Software Engineer

  • Designed and deployed ETL pipelines to process large volumes of PDF documents from S3, including conversion to images, text extraction, and structured JSON generation via the OpenAI API, before indexing into Elasticsearch.
  • Automated Elasticsearch schema synchronization by developing Airflow workflows for versioning, reindexing, and alias management.
  • Developed automation scripts to initialize new Elasticsearch clusters and streamline environment setup.
  • Integrated with Procore's API to extract construction documents into Elasticsearch for advanced search and analytics.
  • Deployed complete multi-server environments (EC2 instances with Airflow, Autopilot, backend API, and frontend) on AWS, ensuring scalable infrastructures compliant with client requirements.
  • Wrote unit tests for the backend library to ensure code reliability and maintainability.
